Title: Topology of biomolecular chains and self-trapping of an excitation
Abstract: To the problem of the excitation self-trapping in the quasi one dimensional biomolecular structures was devoted numerous investigations. But in these investigations, macromolecules were regarded mainly as linear structures, neglecting the influence of the topology of the macromolecule on the process of the exciton self-trapping. It is clear that the taking into consideration of the curved shape with interlaced points of the macromolecule by itself, significantly complicates the considerations of physical phenomena occurring in such systems. On the other hand, twisted forms of macromolecular chains in which the particular structural elements become spatially very close to each other, become a source of additional local interactions of the macromolecular structure elements. Such interactions can significantly alter the process of the excitation self-trapping. We intend to analyze the influence of the regularly distributed interlaced points of the twisted single chain macromolecule to the effective mass of the self-trapped excitation. We taking into account the influence of the temperature, considering that vibron excitation is in thermal equilibrium with the surrounding thermal bath.
